Process and facility engineering firm ranks No. 25 among firms with 10 to 49 employees and No. 66 among multidiscipline firms.
DAYTON, Ohio, October 15, 2026: ADF Engineering, a multidisciplinary process and facility engineering firm serving food, feed and industrial manufacturers, has been named a 2026 Best Firm to Work For by Zweig Group, a consulting, research and education firm for the architecture, engineering and construction (AEC) industry. ADF ranked No. 25 in the 10 to 49 employees category and No. 66 among multidiscipline firms.
Ranked by the People Who Know ADF Best
The Best Firm to Work For Award recognizes AEC workplaces based on a combination of employee feedback and firm-provided data. It evaluates culture, employee experience, professional development and workplace practices. Because employee feedback is central to the rankings, the award reflects how ADF’s own team experiences the firm.
“This recognition is special because it comes from our own people,” said Alex Fishman, president of ADF Engineering. “Our engineers and staff bring the knowledge and care that clients count on in their plants every day. We are proud to build a place where talented people want to grow their careers, and grateful to the team that makes ADF what it is.”
Lasting Client Relationships
That culture carries into client work. According to the company, more than 85 percent of ADF’s business comes from returning clients across food, feed, consumer products, manufacturing and other industrial sectors. ADF has completed more than 5,000 engineering projects for more than 1,700 clients, including Fortune 500 leaders.

Zweig Group celebrated the 2026 Best Firms to Work For at the ElevateAEC Conference and Awards Gala, Sept. 29 to Oct. 1 in Park City, Utah. The full list of winners is available on The Zweig List.
